Kill A Watt

You can read the writing on the product OR you can actually measure it using a device like the Kill A Watt. The second way is better for two reasons: It’s more educational and fun, and some product ratings are approximate. Some products use different amounts of power at different settings. For example, a loudspeaker will use way less power than its rating if you’re listening to music at moderate levels. So get yourself a Kill A Watt and get scientific!
